Utah biologist wins 2011 AAAS Public Engagement with Science Award
The American Association for the Advancement of Science has named Nalini M.

Researchers discover new culprit in atherosclerosis
A new study by NYU Langone Medical Center researchers identified a new culprit that leads to atherosclerosis, the accumulation of fat and cholesterol that hardens into plaque and narrows arteries.

Climate change is altering mountain vegetation at large scale
Climate change is having a more profound effect on alpine vegetation than at first anticipated, according to a study carried out by an international group of researchers and published in Nature Climate Change.

2 genes affect anxiety, behavior in mice with too much MeCP2
The anxiety and behavioral issues associated with excess MeCP2 protein result from overexpression of two genes (Crh [corticotropin-releasing hormone] and Oprm 1 [mu-opioid receptor MOR 1]), which may point the way to treating these problems in patients with too much of the protein, said Baylor College of Medicine scientists.

European mountain vegetation shows effects of warmer climate
Researchers from 13 countries report clear and statistically significant evidence of a continent-wide warming effect on mountain plant communities in Europe.

Team finds a better way to gauge the climate costs of land use changes
Those making land use decisions to reduce the harmful effects of climate change have focused almost exclusively on greenhouse gases -- analyzing, for example, how much carbon dioxide is released when a forest is cleared to grow crops.

Exercise in a pill may protect against extreme heat sensitivity
A molecule identified by researchers at Baylor College of Medicine may reduce the threat of heat-induced death in people with a genetic sensitivity to the ill effects of high temperatures.

New form of graphene could prevent electronics from overheating and revolutionize thermal management
A new form of graphene created by researchers at The University of Texas at Austin could prevent laptops and other electronics from overheating, ultimately, overcoming one of the largest hurdles to building smaller and more powerful electronic devices.

New test spots early signs of inherited metabolic disorders
A team of scientists, led by researchers at the University of California, San Diego School of Medicine and Zacharon Pharmaceuticals, have developed a simple, reliable test for identifying biomarkers for mucopolysaccharidoses, a group of inherited metabolic disorders that are currently diagnosed in patients only after symptoms have become serious and the damage possibly irreversible.

'Couch potato pill' might stop heat stroke too
In a new study published in Nature Medicine, scientists discovered what they believe is one of the first drugs to combat heat stroke.

Simpler times: Did an earlier genetic molecule predate DNA and RNA?
In an article released online today in the journal Nature Chemistry, Chaput and his group describe the Darwinian evolution of functional TNA molecules from a large pool of random sequences.

Graphene reveals its magnetic personality
Can organic matter behave like a fridge magnet? Scientists from the University of Manchester have now shown that it can.

Global warming caused by greenhouse gases delays natural patterns of glaciation, researchers say
Unprecedented levels of greenhouse gases in the Earth's atmosphere are disrupting normal patterns of glaciation, according to a study co-authored by a University of Florida researcher and published online Jan.

Colorado mountain hail may disappear in a warmer future
Summertime hail could all but disappear from the eastern flank of Colorado's Rocky Mountains by 2070, according to a new modeling study by scientists from NOAA and several other institutions.

Evolution of complexity recreated using 'molecular time travel'
In a study in Nature, a team of scientists demonstrate how just a few small, high-probability mutations increased the complexity of a molecular machine more than 800 million years ago.
